Automatically traveling floor dust collecting appliance, and running wheel, in particular for a floor dust collecting appliance
First Claim
1. An automatically traveling floor dust collecting appliance comprising:
- at least one running wheel comprising an axis of rotation, a hub, and a tire forming a tire contact area merging radially inwardly into oppositely situated first and second side faces forming a conical opening contour of the tire in an outward direction, wherein the tire comprises an elastic material and profile blocks provided one after the other in a peripheral direction and associated with the first and second side faces respectively, wherein each of the profile blocks forms a respective tire contact area part of the tire contact area having a respective profile sloping downwardly in cross-section toward a center of the tire and forms a respective side face part of the side face associated with the profile block, wherein the profile block, at a first transition between the tire contact area part and the side face part, radially and in a direction of the axis of rotation, forms a farthest protruding portion of the tire contact area of the tire, wherein the profile block merges into a step surface, and wherein the step surface is lowered with respect to the tire contact area for one half to three times of an elevation of the profile starting from the center up to a second transition into the side face associated with the profile block.

Abstract
An automatically traveling floor dust collecting appliance has at least one running wheel having an axis of rotation, a hub, and a tire forming a tire contact area merging radially inwardly into two oppositely situated side faces. The tire, which includes elastic material, has profile blocks, each forming a part of the tire contact area and provided one after the other in the peripheral direction. A running wheel is also provided, in particular for a floor dust collecting appliance. The part of the tire contact area formed by a profile block has a profile which in its cross-section slopes downwardly toward the center. This profile block at the same time forms a part of an associated side face. The profile block, at this transition, radially and in the direction of the axis of rotation, forms a farthest protruding portion of the tire contact area of the tire.
